Description

Technical Field

[0001] This invention relates to the field of metal welding equipment technology, specifically a multi-angle welding device for steel plate processing. Background Technology

[0002] The technology of metal cutting and welding equipment continues to improve with the progress of society. For example, welding is required in the processing of steel plate metal. As steel structural components become larger and more complex, steel plate welding often requires multiple weld seams to be completed at different angles and positions. For example, the patent with announcement number CN216680890U describes a welding device for processing galvanized steel sheets, which includes a base plate, a clamping plate, a mounting plate, a stroke column, a support plate, a rotating plate, and a screw. The rotating plate is arranged between the support plates, and the base plate is arranged on both sides below the rotating plate. The upper end of the base plate has a placement groove. The mounting plate is arranged above the rotating plate, and the clamping plate is arranged between the mounting plates. A sealing ring is embedded in the mounting plate, and a stroke column is slidably inserted into the sealing ring. The mounting plate has a screw hole and a positioning hole, and a screw is rotatably inserted into the screw hole. For example, a high-efficiency gantry-type pipe welding machine, as disclosed in patent CN215824707U, includes a frame, a second hydraulic telescopic rod, and a support frame. A track frame is provided below the frame, and a first hydraulic telescopic rod is provided through the upper end of the frame. The lower end of the first hydraulic telescopic rod is connected to a fixed frame. The second hydraulic telescopic rod is provided through the rotating frame, and a clamp is connected to the lower end of the second hydraulic telescopic rod. The frame can move on the track frame to adjust the position of the welding device, which facilitates the welding processing of both ends of the pipe. The welding device can be operated and adjusted under the action of the third and fourth hydraulic telescopic rods. For example, the patent with publication number CN215824686U describes an assembly machine for welding steel plates that is easy to rotate, which includes a lifting mechanism, a rotating mechanism, and a processing mechanism. The base is provided with a first hydraulic telescopic rod, one end of the positive and negative threaded rod is connected to the output end of a motor, the side of the moving carriage away from the base is provided with a support plate, the bracket is provided at the four corners of the upper surface of the base, and two second moving blocks are symmetrically arranged on the first moving block. The motor can drive the slider on the positive and negative threaded rod to move, and the slider can drive the limit block to move, which is convenient for limiting the flange plates of different widths. Most of the aforementioned existing technologies improve the overall structure. However, when existing steel plate welding equipment needs to perform welding operations on two sets of steel plates at different angles during operation, most welding equipment uses independent support blocks or angle shims to elevate one of the steel plates. Angle adjustment relies on manual trial and error based on experience, which is not only inefficient but also makes it difficult to guarantee angle accuracy. Especially when welding different angles such as 30°, 45°, 60°, and 120°, different angle shims need to be replaced or the support height needs to be readjusted, making the operation cumbersome. For situations where it is necessary to mass-produce welded components at different angles, frequent tooling changes severely restrict production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-angle welding device for steel plate processing, which solves the problem in the background art where welding equipment uses independent support blocks or angle shims to elevate one of the steel plates. Angle adjustment relies on manual trial and error based on experience, which is not only inefficient but also makes it difficult to guarantee angle accuracy. Especially when welding different angles such as 30°, 45°, 60°, and 120°, different angle shims need to be replaced or the support height needs to be readjusted, which is cumbersome. For batch production of components with different angles, frequent tooling changes severely restrict production efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a multi-angle welding device for steel plate processing, comprising a bearing welding base, a hydraulic drive component installed on the outer side of the bearing welding base, and a bearing docking assembly connected to the output end of the hydraulic drive component, wherein the steel plate workpiece to be welded is placed on the upper end of the bearing docking assembly, and a welding component is installed in the middle of the inner side of the bearing welding base, wherein two sets of steel plates are welded by the welding component; a limiting docking component is nested on the outer side of the bearing docking assembly, and a bearing mechanism for changing the welding angle of the steel plate workpiece is provided between the limiting docking component and the bearing docking assembly.

[0005] Furthermore, the bearing mechanism is provided with an arc-shaped guide component, which is installed at the output end of the hydraulic drive component. The arc-shaped guide component and the bearing docking component rotate and dock with each other. A vertical bearing component is fixedly connected to the upper outer side of the hydraulic drive component, and the vertical bearing component and the lower end of the bearing docking component are in contact and bearing each other. An external abutment component is fixedly connected to the outer side of the output end of the hydraulic drive component.

[0006] Furthermore, the bearing docking assembly has a reserved guide groove inside, and a reserved meshing assembly is nested inside the reserved guide groove. The lower end of the reserved meshing assembly corresponds to the outer side of the external abutment. A gear docking assembly is rotatably connected inside the reserved guide groove, and the gear docking assembly and the reserved meshing assembly mesh with each other. An internal guide meshing assembly meshes with the outer side of the gear docking assembly. The internal guide meshing assembly is located inside the bearing docking assembly, and the outer side of the internal guide meshing assembly meshes with the outer side of the limiting docking member. A guide elastic transmission roller is rotatably connected to the outer side of the limiting docking member.

[0007] Furthermore, the arc-shaped guide component controls the unidirectional rotation of the load-bearing docking component. As the load-bearing docking component disengages from the contact bearing state with the vertical load-bearing component, the hydraulic drive component pushes the load-bearing docking component to form an inward angular movement through the arc-shaped guide component.

[0008] Furthermore, during the movement of the bearing docking assembly, the reserved meshing assembly at its lower end will contact the external abutment. The abutment of the external abutment causes the reserved meshing assembly to move along the interior of the reserved guide groove. The reserved meshing assembly, in conjunction with the gear docking assembly, drives the built-in guide meshing assembly to move synchronously.

[0009] Furthermore, the lower end of the limiting docking component is provided with a guide support structure, which improves the guiding load-bearing strength of the limiting docking component on the steel plate workpiece; the guide support structure is provided with a return spring, and the return spring is fixedly connected to the outside of the built-in guide engagement assembly, and the return spring is connected to the inside of the load-bearing docking assembly; a built-in vertical corrugated liquid bladder assembly is provided between the load-bearing docking assembly and the built-in guide engagement assembly.

[0010] Furthermore, the outer side of the built-in vertical corrugated liquid bladder assembly is connected to a supply hose, and the supply hose passes through the inner side of the limiting docking member. The lower end of the limiting docking member is connected to an auxiliary guide liquid bladder assembly, and the auxiliary guide liquid bladder assembly and the supply hose are interconnected.

[0011] Furthermore, the built-in guide engagement assembly forms a sliding structure along the inner side of the bearing docking assembly via a reset spring, and the outer side of the built-in guide engagement assembly is integrally set with the limiting docking member.

[0012] Furthermore, the built-in guide engagement assembly applies pressure to the built-in vertical corrugated liquid bladder assembly along the inner side of the bearing docking assembly, and the built-in vertical corrugated liquid bladder assembly provides supply treatment to the interior of the auxiliary guide liquid bladder assembly through the supply hose.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This multi-angle welding device for steel plate processing is equipped with a bearing mechanism that can change the welding angle of the steel plate workpiece. Through two sets of symmetrically arranged hydraulic drive components, the steel plates placed through the bearing docking assembly are independently and synchronously driven to rotate around the same rotation axis. When the two hydraulic drive components push the corresponding steel plates upward to make angle movements, the rotation angle of the steel plate is linearly related to the stroke of the drive rod. The operator can quickly calculate the extension of the drive rod according to the required angle without repeated trial and error. This symmetrical adjustment method ensures that the angle adjustment of the two steel plates does not interfere with each other, and the adjustment process is smooth and continuous. It can achieve any angle adjustment within the range of 0-180°. In conjunction with the movable welding equipment inside the device, it can stably move and weld the contact parts of the two sets of steel plates that form angle contact, thereby ensuring the stability of the angle welding. Furthermore, the two sets of hydraulic drive components are symmetrically arranged and act on the bottom of the two steel plates respectively. When the hydraulic drive components push upward, the two steel plates are subjected to symmetrical support forces, and the lateral components generated by each cancel each other out, so that the mating edges of the two steel plates always remain aligned. Compared with the single-sided drive scheme, this avoids the offset and torsional deformation of the steel plates during the angle adjustment process, ensures that the weld gap is uniform and consistent, and lays the foundation for high-quality welding. Furthermore, during the movement of the bearing docking assembly carrying the steel plate workpiece, the reserved meshing assembly at its lower end will contact the external abutment. Through the abutment of the external abutment, the reserved meshing assembly moves along the interior of the reserved guide groove, causing it to work with the meshing gear docking assembly to drive the built-in guide meshing assembly to move synchronously downward along the interior of the bearing docking assembly. This, together with the limiting docking component, provides auxiliary limiting for the angle movement of the workpiece, preventing positional deviation during the welding process. When the hydraulic drive component reaches the set height, the steel plate automatically remains stable under the support of gravity and the limiting docking component, eliminating the need for additional manual clamping. Simply operating the lifting and lowering of the drive rod is sufficient to simultaneously complete the angle setting and initial fixing, shortening the clamping time and making the operation convenient. Furthermore, a guiding support structure is provided to enhance the guiding and bearing strength of the limiting docking component on the steel plate workpiece. As the built-in guiding engagement assembly moves downward along the inner side of the bearing docking component, it applies pressure to the contacting built-in vertical corrugated liquid bladder assembly. This allows the built-in vertical corrugated liquid bladder assembly to supply fluid to the interior of the auxiliary guiding liquid bladder assembly through the supply hose, thereby continuously increasing the contact force at the lower end of the limiting docking component and maintaining its limiting strength as the steel plates are docked, thus providing a basic guarantee for the subsequent welding state.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1: Please refer to Figures 1-9This invention provides the following technical solution: a multi-angle welding device for steel plate processing. To address the problem that welding equipment uses independent support blocks or angle shims to elevate one of the steel plates, and angle adjustment relies on manual trial and error based on experience, which is not only inefficient but also makes it difficult to guarantee angle accuracy. Especially when welding at different angles, different angle shims need to be replaced or the support height readjusted, making the operation cumbersome. For batch production of welded components at different angles, frequent tooling changes severely restrict production efficiency. The invention discloses a device comprising: a hydraulic drive component 2 installed on the outer side of a bearing welding base 1, with the output end of the hydraulic drive component 2 connected to a bearing docking assembly 4; the upper end of the bearing docking assembly 4 holds the steel plate workpiece to be welded; a welding component is installed in the middle of the inner side of the bearing welding base 1, and the welding component performs welding on two sets of steel plates; a limiting docking component 10 is nested on the outer side of the bearing docking assembly 4, and a bearing mechanism for changing the welding angle of the steel plate workpiece is provided between the limiting docking component 10 and the bearing docking assembly 4.

[0018] The bearing mechanism is equipped with an arc-shaped guide component 3, which is installed at the output end of the hydraulic drive component 2. The arc-shaped guide component 3 and the bearing docking component 4 are rotatably docked. A vertical bearing component 5 is fixedly connected to the upper outer side of the hydraulic drive component 2, and the vertical bearing component 5 and the lower end of the bearing docking component 4 are in contact and bearing each other. An external abutment component 6 is fixedly connected to the outer side of the output end of the hydraulic drive component 2. A reserved guide groove 16 is provided inside the bearing docking component 4, and a reserved meshing component 7 is nested inside the reserved guide groove 16. The lower end of the reserved meshing component 7 corresponds to the outer side of the external abutment component 6. A gear docking component 8 is rotatably connected inside the reserved guide groove 16, and the gear docking component 8 and the gear docking component 6 are rotatably docked. The reserved meshing components 7 mesh with each other. The outer side of the gear docking component 8 is meshed with a built-in guide meshing component 9, which is located inside the bearing docking component 4. The outer side of the built-in guide meshing component 9 is docked with the outer side of the limiting docking component 10. The outer side of the limiting docking component 10 is rotatably connected to a guide elastic transmission roller 11. The arc-shaped guide component 3 controls the unidirectional rotation of the bearing docking component 4. As the bearing docking component 4 disengages from the contact bearing state with the vertical bearing component 5, the hydraulic drive component 2 pushes the bearing docking component 4 to form an inward angle movement through the arc-shaped guide component 3. During the movement of the bearing docking component 4, the reserved meshing component 7 at its lower end will contact the external abutment component 6. The resistance causes the reserved meshing component 7 to move along the interior of the reserved guide groove 16. The reserved meshing component 7, in conjunction with the gear docking component 8, drives the built-in guide meshing component 9 to move synchronously. After the steel plates to be welded are placed on the upper end of the bearing docking component 4, the two sets of symmetrically arranged hydraulic drive components 2 are driven to independently and synchronously drive the steel plates placed through the bearing docking component 4 to rotate around the same axis of rotation. When the two hydraulic drive components 2 push the corresponding steel plates upward to make angular movements, the rotation angle of the steel plates is linearly related to the stroke of the drive rod. The operator can quickly calculate the extension of the drive rod according to the required angle without repeated trial and error. This symmetrical adjustment method ensures that the angle adjustment of the two steel plates does not interfere with each other, and the adjustment process is smooth and continuous. It can achieve any angle adjustment within the range of 0-180°. With the help of the movable welding equipment inside the equipment, it can stably and dynamically weld the contact parts of two sets of steel plates that form an angle contact. Two sets of hydraulic drive components 2 are symmetrically arranged and act on the bottom of the two steel plates respectively. When the hydraulic drive components 2 push upward, the two steel plates are subjected to symmetrical support forces. The lateral components generated by each cancel each other out, so that the butt joint edges of the two steel plates always remain aligned. Compared with the single-side drive scheme, it avoids the offset and torsional deformation of the steel plates during the angle adjustment process and ensures that the weld gap is uniform. The welding operation is carried out by moving the welding components along the weld direction through manual or automatic adjustment. The welding components are connected to an external welding power source for welding the butt joint of the two steel plates. During the movement of the load-bearing docking assembly 4 of the steel plate workpiece, the reserved meshing assembly 7 at its lower end will contact the external abutment 6. Through the abutment of the external abutment 6, the reserved meshing assembly 7 moves along the interior of the reserved guide groove 16, which in turn drives the internal guide meshing assembly 9 to move synchronously along the interior of the load-bearing docking assembly 4. This, together with the limiting docking component 10, provides auxiliary limiting for the angle movement of the workpiece, preventing positional deviation during the welding process. When the hydraulic drive component 2 reaches the set height, the steel plate automatically remains stable under the support of gravity and the limiting docking component 10. No additional manual clamping operation is required; simply operating the lifting and lowering of the drive rod is sufficient to simultaneously complete the angle setting and initial fixing.

[0019] Example 2: Based on Example 1, a guide support structure is also disclosed, the specific structure of which is as follows: The lower end of the limiting docking part 10 is provided with a guide support structure, which improves the guiding load-bearing strength of the limiting docking part 10 on the steel plate workpiece. The guide support structure is equipped with a return spring 12, which is fixedly connected to the outside of the built-in guide engagement assembly 9. The return spring 12 is connected to the inside of the bearing docking assembly 4. A built-in vertical corrugated liquid bladder assembly 13 is provided between the bearing docking assembly 4 and the built-in guide engagement assembly 9. A supply hose 14 is connected to the outside of the built-in vertical corrugated liquid bladder assembly 13, and the supply hose 14 passes through the inside of the limiting docking member 10. An auxiliary guide liquid bladder assembly 15 is connected to the lower end of the limiting docking member 10, and the auxiliary guide liquid bladder assembly 15 is connected to the supply hose 14. The built-in guide engagement assembly 9 forms a sliding structure along the inside of the bearing docking assembly 4 through the return spring 12. The outside of the built-in guide engagement assembly 9 is integrated with the limiting docking member 10. The built-in guide engagement assembly 9 slides inward along the inside of the bearing docking assembly 4. The vertical corrugated liquid bladder assembly 13 is pressurized, and the built-in vertical corrugated liquid bladder assembly 13 supplies the auxiliary guide liquid bladder assembly 15 through the supply hose 14. As the built-in guide engagement assembly 9 moves downward along the inner side of the bearing docking assembly 4, it pressurizes the contacting built-in vertical corrugated liquid bladder assembly 13, increasing its internal pressure. This allows the built-in vertical corrugated liquid bladder assembly 13 to supply the auxiliary guide liquid bladder assembly 15 through the supply hose 14, thereby continuously increasing the contact force at the lower end of the limiting docking member 10, and maintaining its limiting strength as the steel plates dock. When the built-in guide engagement assembly 9 resets upward under the action of the return spring 12, the built-in vertical corrugated liquid bladder assembly 13 contracts under its own elastic restoring force and negative pressure, the hydraulic oil flows back, and the auxiliary guide liquid bladder assembly 15 contracts accordingly, releasing the auxiliary clamping force.
